发明名称 High voltage GaN transistors
摘要 A multiple field plate transistor includes an active region, with a source, a drain, and a gate. A first spacer layer is over the active region between the source and the gate and a second spacer layer over the active region between the drain and the gate. A first field plate on the first spacer layer is connected to the gate. A second field plate on the second spacer layer is connected to the gate. A third spacer layer is on the first spacer layer, the second spacer layer, the first field plate, the gate, and the second field plate, with a third field plate on the third spacer layer and connected to the source. The transistor exhibits a blocking voltage of at least 600 Volts while supporting a current of at least 2 Amps with an on resistance of no more than 5.0 m&OHgr;-cm2, of at least 600 Volts while supporting a current of at least 3 Amps with an on resistance of no more than 5.3 m&OHgr;-cm2, of at least 900 Volts while supporting a current of at least 2 Amps with an on resistance of no more than 6.6 m&OHgr;-cm2, or a blocking voltage of at least 900 Volts while supporting a current of at least 3 Amps with an on resistance of no more than 7.0 m&OHgr;-cm2.
